Hi there,
I'm writing a little package to handle fractional derivatives, and it
works well, with one exception. This is one of my definitions:
D[f_[x_],{x_,q_}] := (f^q)[x] /; (Head[x] === Symbol) && (Head[q] ===
Real || Head[q] === Rational || Head[q] === Complex)
This is because I want the half-derivative of f[x] to display as
f(superscript 1/2)[x]. Unfortunately, instead, Mathematica displays
this as it would Sqrt[f][x], which looks nonsensical. Is there any way
in output that I can get it to preserve the superscript 1/2 (half)
rather than displaying a square root sign? Am I being clear here? If
not, let me know and I will elucidate!!
Thanks, cheers,
Adrian Cable.
